Hello

I just bought Galaxy S4 , while it is a wonderful phone , I am having issues in transferring data to the micro SD card. I have inserted 32 GB , class 10 card in the phone. Whenever , I try to connect phone to my PC and try to do a data transfer , it always comes up with the error that micro SD card is write protected , remove write protection in order to proceed with data transfer.

Appreciate help in getting rid of this annoying issue.

Tnx

Have you tried formatting the card while it's in your phone? To do this, go into Settings > More > Storage > Format SD Card. This will wipe the card, but should ensure it's in a state that the phone is happy with.

It's also possible that the card is on its way out. This is more likely on the cheap, no-name cards but can also happen with name brand.

64GB cards use a different type of file system, exFAT, instead of the usual FAT32. I know that Samsung have licensed the exFAT technology from Microsoft, but can't distribute the relevant source code with their kernel source because of the licensing terms. It's possible that there are bugs in that code that could cause problems.

The other option is that the file system on the card has been slightly corrupted. This is a possibility with FAT-type file systems, as they lack a feature (journaling) that helps protect against partial writes. The best thing you can do is to copy whatever content you can of the card, then format it in the phone. You could also download some software for your computer that will let you format the card as FAT32, which is widely-supported and use less likely to cause issues.

humm, though i had it solved. im wondering if the file is too big, or the video ratio, still having problems trying add video. the files arent too big say between 300 and 1gb my guess is its a android fault somewhere. the ones that do load on ok work fine for a day and some that i dont touch seem to not wanna work the nextday either.
might try today to shrink the video

64 gig cards work fine in an S2 if you format in the phone and end up with it as fat32, exfat's only usefull change sorts out the 2 gig file size limit, which helps when wanting to store HD movies, but I have never bothered with that on my phone.

Im starting to go crazy, files just disappear and the folders rename folders or files that are in the microSD change their names starting with a "µ" e.g. NES to µES. some songs play then are unreadible ive tried tested fat32 and formatted it in the phone as exfat.

Sounds like you might have a faulty SD Card.

I have had similar issues on an off brand trademe full size SD card a while back. Ended up working ok on my arduino tho so I suspect it was the controller not the flash memory in the card.
